What moves the price of replacement conservatory roofs
- Roof type
Polycarbonate is the cheapest, glass costs more, a hybrid costs more again and a solid tiled roof costs the most.
- Size and shape
A bigger roof needs more material and more labour. Complex shapes with several facets or a hip cost more than a simple pitched roof.
- Structure
An older frame may need strengthening before a heavier roof goes on. A glass or solid roof is much heavier than polycarbonate.
- Access
Scaffolding adds to the price where the roof cannot be reached safely from the ground.
- Where you live
London and the South East run dearer than the North of England and Wales.
